Simplified 1D Empirical Model for Volumetric Behavior of High-Carbonate Clay
(2019)
The Guadalquivir blue marl is a high plasticity overconsolidated carbonate clay. This soil presents an elevated fragility and high susceptibility to moisture changes. These characteristics have caused many geotechnical ...

Optimal ductility enhancement of RC framed buildings considering different non-invasive retrofitting techniques
(Elsevier, 2021-09-01)
Existing RC framed buildings lack significant ductility, especially when they have been built with pre-code criteria. Improving their ductile capacity can help to prevent them from the brittle collapse mechanism and to ...

A deterministic seismic risk macrozonation of Seville
(Springer, 2021-11-10)
The seismicity of the southwestern Iberian Peninsula is moderate but large events with long return periods occur (≈ 200 years). This exceeds the life of various generations, making the population unacquainted with the ...

An index-based method for evaluating seismic retrofitting techniques. Application to a reinforced concrete primary school in Huelva
(Public Library of Science, 2019-04)
A project named PERSISTAH (Projetos de Escolas Resilientes aos SISmos no Território do Algarve e de Huelva, in Portuguese) is being developed. It aims to cooperatively assess and improve the seismic vulnerability of primary ...

The 1531 earthquake revisited: loss estimation in a historical perspective
(Springer, 2018)
In this research, the 1531 earthquake is revisited. This was one of the major earthquakes that affected Portugal and, specifically, Lisbon. According to coeval sources, between 1000 and 30,000 casualties were caused in ...

Assessment of specific structural and ground-improvement seismic retrofitting techniques for a case study RC building by means of a multi-criteria evaluation
(Elsevier, 2022)
Existing reinforced concrete (RC) structures might not comply with current seismic codes due to their aseismic design and construction date. By seismically retrofitting them, it is possible to improve their seismic ...

Influence of the constructive features of RC existing buildings in their ductility and seismic performance
(Springer, 2021)
This paper aims to analyse the ductility of existing buildings to evaluate its influence in their 14 seismic performance. This has been achieved through the retrospective analysis of an existing 15 building in accordance ...

Regional correlations for estimating seismic amplification. Implications for loss assessment in SW Iberia
(Elsevier, 2020)
Most earthquake-related losses are enhanced by soil amplification phenomena, especially in areas where high vulnerability assets coexist. These mechanisms are frequently inferred from empirical formulas. These procedures ...

Analysis of the soil structure-interaction effects on the seismic vulnerability of mid-rise RC buildings in Lisbon
(Elsevier, 2022)
Soil-structure interaction (SSI) effects are usually omitted in the seismic vulnerability analyses of buildings. However, it has been proved that they might notably affect their seismic performance. In fact, European ...

Diferentes enfoques para la fractura dúctil basados en la metodología phase-field: Aplicación a modelos de plasticidad asociada y no asociada
(Sociedad Española de Integridad Estructural, 2022)
Los procesos de fractura son una de las principales causas de fallo en diferentes materiales y estructuras en diferentes aplicaciones en Ingenier´ıa. Por ello, a lo largo de las ´ultimas d´ecadas, su estudio ha estado ...
